A Heuristic is a technique to solve a problem faster than classic methods, or to find an approximate solution when classic methods cannot. This is a kind of a shortcut as we often trade one of optimality, completeness, accuracy, or precision for speed. A Heuristic (or a heuristic function) takes a look at search algorithms. At each branching step, it evaluates the available information and makes a decision on which branch to follow.

(Parallel Clustering Algorithm Optimization for Large-Scale Data Analytics)
Clustering은 데이터 분석에 가장 널리 쓰이는 방법 중 하나로 주어진 데이터를 유사성에 기초하여 여러 개의 그룹으로 나누는 작업이다. 하지만 Clustering 방법의 높은 계산 복잡도 때문에 대용량 데이터 분석에는 잘 사용되지 못하고 있다. 최근 이 높은 복잡도 문제를 해결하기 위해 많은 연구가 Hadoop, Spark와 같은 분산 컴퓨팅 방식을 적용하고 있지만 기존 Clustering 알고리즘을 분산 환경에 최적화시키는 것은 쉽지 않다. 특히, 효율성을 높이기 위해 정확성을 손실하는 문제 그리고 여러 작업자들 간의 부하 불균형 문제는 알고리즘을 분산처리 할 때 발생하는 대표적인 문제이다. 본 세미나에서는 대표적 Clustering 알고리즘인 DBSCAN을 분산처리 할 때 발생하는 여러 도전 과제에 초점을 맞추고 이를 해결 할 수 있는 새로운 해결책을 제시한다. 실제로 이 방법은 최신 연구의 방법과 비교하여 정확도 손실 없이 최대 180배까지 알고리즘의 성능을 향상시켰다.

5. Conclusions
Outlier detection is very interesting, useful and challenging problem in the field of data mining. Because of
sparse data clustering algorithm which are based on distance will not work to find outliers in spatial data.
Problem of finding irregular feature in spatial data need to be explore. Many existing approaches have
been proposed to overcome the problem of outlier detection in spatial Geographic data. In this paper an
efficient clustering and density based outlier detection framework has been proposed. The process of
outlier detection has been categorized into two steps in the first step data has been clustered together based
on any density based DBSCAN algorithm and in the second stage outlier detection is performed using LOF.
The purpose is to perform clustering and outlier mining simultaneously to improve feasibility of framework.
To verify the efficiency and robustness of proposed method, comparative study of proposed approach and
several existing approaches are presented in detail, various simulation results demonstrate the
effectiveness of the proposed approach.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

4. Properties of Search Algorithms
• Following are the four essential properties of search algorithms to compare
the efficiency of these algorithms:
• Completeness: A search algorithm is said to be complete if it guarantees to
return a solution if at least any solution exists for any random input.
• Optimality: If a solution found for an algorithm is guaranteed to be the
best solution (lowest path cost) among all other solutions, then such a
solution for is said to be an optimal solution.
• Time Complexity: Time complexity is a measure of time for an algorithm
to complete its task.
• Space Complexity: It is the maximum storage space required at any point
during the search, as the complexity of the problem.

5. Types of search algorithms
Based on the search problems we can classify the
search algorithms into
– uninformed (Blind search) search and
– informed search (Heuristic search) algorithms.

Department of CSE (AI/ML)
7. Uninformed/Blind Search
•Uninformed search applies a way in which search tree is
searched without any information about the search space like
initial state operators and test for the goal, so it is also called
blind search.
•Don’t have any domain knowledge .
•It examines each node of the tree until it achieves the goal node.
It can be divided into five main types:
– Breadth-first search
– Uniform cost search
– Depth-first search
– Iterative deepening depth-first search
– Bidirectional Search

8. Informed Search
• Informed search algorithms use domain knowledge. In an
informed search, problem information is available which
can guide the search.
• Informed search strategies can find a solution more
efficiently than an uninformed search strategy. Informed
search is also called a Heuristic search.
• A heuristic is a way which might not always be
guaranteed for best solutions but guaranteed to find a
good solution in reasonable time.
• An example of informed search algorithms is a traveling
salesman problem.
• Greedy Search
• A* Search

9. Breadth-first Search
• Breadth-first search is the most common search
strategy for traversing a tree or graph. This
algorithm searches breadthwise in a tree or graph,
so it is called breadth-first search.
• BFS algorithm starts searching from the root node
of the tree and expands all successor node at the
current level before moving to nodes of next
level.
• The breadth-first search algorithm is an example
of a general-graph search algorithm.
• Breadth-first search implemented using FIFO
queue data structure.
2/23/2023 Department of CSE (AI/ML) 9
10. Algorithm
• Step 1: SET STATUS = 1 (ready state) for each node in
G
• Step 2: Enqueue the starting node A and set its
STATUS = 2 (waiting state)
• Step 3: Repeat Steps 4 and 5 until QUEUE is empty
• Step 4: Dequeue a node N. Process it and set its
STATUS = 3 (processed state).
• Step 5: Enqueue all the neighbours of N that are in the
ready state (whose STATUS = 1) and set
their STATUS = 2
(waiting state)
[END OF LOOP]
• Step 6: EXIT

12. • In the example given below, there is a directed
graph having 7 vertices.
• In the above graph, minimum path 'P' can be
found by using the BFS that will start from
Node A and end at Node E.
• The algorithm uses two queues, namely
QUEUE1 and QUEUE2.
• QUEUE1 holds all the nodes that are to be
processed, while QUEUE2 holds all the nodes
that are processed and deleted fromQUEUE1.

16. Applications of BFS algorithm
• BFS can be used to find the neighboring
locations from a given source location.
• BFS can be used in web crawlers to create web
page indexes.
• BFS is used to determine the shortest path and
minimum spanning tree.
2/23/2023 Department of CSE (AI/ML) 16
17. DFS (Depth First Search) algorithm
• It is a recursive algorithm to search all the
vertices of a tree data structure or a graph.
• The depth-first search (DFS) algorithm starts with
the initial node of graph G and goes deeper until
we find the goal node or the node with no
children.
• Because of the recursive nature, stack data
structure can be used to implement the DFS
algorithm.
• The process of implementing the DFS is similar
to the BFS algorithm.
2/23/2023 Department of CSE (AI/ML) 17
18. The step by step process to implement the DFS traversal
is given as follows -
• First, create a stack with the total number of vertices in
the graph.
• Now, choose any vertex as the starting point of
traversal, and push that vertex into the stack.
• After that, push a non-visited vertex (adjacent to the
vertex on the top of the stack) to the top of the stack.
• Now, repeat steps 3 and 4 until no vertices are left to
visit from the vertex on the stack's top.
• If no vertex is left, go back and pop a vertex from the
stack.
• Repeat steps 2, 3, and 4 until the stack is empty.
2/23/2023 Department of CSE (AI/ML) 18
19. Algorithm
• Step 1: SET STATUS = 1 (ready state) for each node in G
• Step 2: Push the starting node A on the stack and set its
STATUS = 2 (waiting state)
• Step 3: Repeat Steps 4 and 5 until STACK is empty
• Step 4: Pop the top node N. Process it and set its STATUS = 3
(processed state)
• Step 5: Push on the stack all the neighbors of N that are in the
ready state (whose STATUS = 1) and set their STATUS = 2
(waiting state)
• [END OF LOOP]
• Step 6: EXIT

22. Applications of DFS
• DFS algorithm can be used to implement the
topological sorting.
• It can be used to find the paths between two
vertices.
• It can also be used to detect cycles in the graph.
• DFS algorithm is also used for one solution
puzzles.
• DFS is used to determine if a graph is bipartite or
not.
